摘　　要：分析了福建武平烟区205个土壤样本的质地、pH值及土壤养分状况,并对不同质地土壤各肥力因子的相关性进行了分析.结果表明:(1)武平烟区植烟土壤砂土占37.07%,壤土占58.05%,黏土占4.88%.(2)不同质地土壤主要养分含量差异均达到极显著水平,全钾达到显著水平,并表现为黏土含量最高,砂土含量最低.壤土全磷含量最高,砂土最低,pH值表现为砂土最高,黏土最低.砂土pH值与有机质、全氮、速效钾均呈极显著负相关,与碱解氮呈显著负相关,全氮与速效钾呈显著正相关,碱解氮与全磷和速效钾呈显著正相关,与有效磷呈极显著正相关.壤土pH值与全磷和全钾呈显著正相关;有机质与全氮和全磷,有效磷与速效钾均呈极显著正相关;全磷与速效钾呈显著正相关.黏土pH值与全氮呈显著负相关.砂土各肥力因子之间的相互影响较大,而壤土和黏土各肥力因子间的相互影响较小.The soil texture, Soil pH and main nutrient of 205 soil samples from Wuping tobacco-areas as well as correlation between main fertility factors in differently textured soil were researched. The results indicated that sand soil, loam soil and clay respectively account for 37.07%, 58.05%, 4.88%. The differences of main nutrient in different soil texture, while total K′being significant, were highly. And the clay’s content of main nutrient was highest, while sand soil was lowest, in the three type textured soil. The content of total P′was showed loam soil was highest and sand soil was lowest. The sand soil’s pH was higher than the clay and loam soil, the clay’s pH was the lowest. Sand： pH value has a very significant negative correlation with organic content, the content of total N and available K, and shows a significant negative correlation with nitrogen; total N shows highly significant positive correlation with nitrogen, and it significantly correlates with available K; nitrogen positively correlates with total P and available K, and highly significantly positively correlates with available P; total P and available P, total K and available K show a highly significant positive correlation. Loam soil： pH shows significant positive correlation with total P and total K; organic matter shows highly significant positive correlation with total N and total P, which are the same with total P and available K; total P significantly positively correlates with available K. Clay： pH significantly negatively correlates with total N; It has great influence in the interrelationship of fertility factors in sand soil, while less in loam soil and clay.
